1. How many compass points are shown in Figure 3-1?
16 compass points (page 27)
2. What direction is halfway between each of the following
directions? (page 27)
a. NE and SW – SE
b. NE and S – ESE
c. WSW and NNW – WNW
/3 3. What direction is opposite each of the following
directions? (page 27)
a. SW – NE
b. NNE – SSW
c. ESE – WNW
4. Examine Fig 3-7 and explain how GPS technology works.
(page 36-37) GPS units pick up radio signals from orbiting GPS
satellites. The GPS unit uses time from the satellites to
calculate its distance from the satellites and to determine its
latitude and longitude. A GPS unit needs signals from at least 3
satellites to determine its location.

5. Give the compass bearings for the following directions
(page 27)
a. N – 0 and 360
b. SSE – 157.5
c. NE – 22.5

6. What is the direction of the following bearings? (page

a. 22.5 – NNE
b. 112.5 – ESE
c. 292.5 – WNW
7. Use the information in fig 3-11 to determine the
direction of each of the numbered arrows.
 #1 - N
 #2 - NW
 #3 - NE
 #4 - E
 #5 – S
/4 8. Using a Mercator projection in an atlas and a protractor,
calculate the bearing of each of the following locations
from Edmonton. (these answers are just approximates)
a. Prince Albert – 90
b. Medicine Hat – 150
c. Kelowna – 225
d. Peace River – 320

11.a) Use your atlas to determine the location of the
following capital cities:
 Ottawa, Canada – 45N 75W
 Cairo, Egypt – 30N 31E
 Santiago, Chile – 33S 70W
 Wellington, New Zealand – 41S 175E
 Kampala, Uganda – 0 32E
b) In which hemisphere is each capital located?
 Ottawa, Canada – NW

 Cairo, Egypt – NE
 Santiago, Chile – SW
 Wellington, New Zealand – SE
 Kampala, Uganda S
12. What is the straight-line distance in kilometers between
/2 each pair of cities? Each pair is located on the same line of
longitude. (page 34) (note: remember that the lines of latitude
are approximately 111 km apart).
a) 20N and 5N – the cities are 15 of latitude apart (20N
– 5N), so the distance between them is 1665 km (15 x
111km)
b) 25N and 17S – the cities are 42 of latitude apart (25N
– 17S) so the distance between them is 4662 km (42 x
111 km)

13. Refer to the map of time zones in Canada and the United
States (fig 3-10)
a) 5pm – Vancouver time is 3 hours behind Toronto
time
b) 7:30am – Winnipeg time is 2.5 hours behind St.
John’s time
c) 11pm – Montreal time is 3 hours ahead of LA time.
14. Must call from Toronto at 10am local time
a) Frankfurt, Germany – 4am - Toronto is 5 time zones
behind Frankfurt.
/5
b) London, England – 5am – Toronto is 5 time zones behind
London.
c) Vancouver, Canada – 1pm – Toronto is 3 time zones
ahead of Vancouver.
d) LA, USA – 1pm – Toronto is 3 time zones ahead of LA.
e) Hong Kong, China – 9pm the night before – Toronto is
13 time hours behind Hong Kong.

15. If your local time is 11am and the time at the prime
meridian is 5:30pm, what is your longitude? (page 38)
Your location is west of the prime meridian since your local
time is 6.5 hours behind UT (the time at the prime meridian).
Because each hour represents one time zone 15 wide, your
longitude is 97.5W (6.5 x 15 degrees).

16. Your local time is 3am and your longitude is 120E. What
time is it at the prime meridian? (page 38)
Since your longitude is 120E you are 8 time zones (120/15)
ahead of UT, the time at the prime meridian. Therefore, UT
is 7pm the night before (8 hours before your local time of
3am)
17. You are on a ship that has 2 chronometers. One gives UT
/2
as 3pm and the other gives your local time as 9am. If your
latitude has been calculated at 62N. (page 39-40)
a) What is your longitude? Your location is west of the
prime meridian since your local time is 6 hours behind UT.
Your longitude is 90W (6 x 150).
b) Consult an atlas to determine in what body of water you
are located.
Your location of 62N 90W is in Hudson Bay.
